How to connect Best in Slot
Install the extension and the Vault
Add Locker Protocol Wallet to Chrome or Brave, and set up the free Locker Vault on a spare phone that stays offline.
Choose "Unisat"
Open Best in Slot, press its connect button and pick "Unisat" in the list, then approve the connection in the extension.
Sign on the offline device
When Best in Slot asks for a signature, the extension shows a QR code. Scan it with the Vault, read the transaction there, approve it, and scan the answer back.
On Bitcoin, the Vault decodes the PSBT itself: every output, the fee as a share of the amount, and any output below the dust limit.
Best in Slot and Locker: questions people ask
Is it safe to use Best in Slot with Locker Protocol Wallet?
The wallet cannot make any site safe, but it changes what an attacker can do: the key never touches the computer, every transaction is shown on the offline device before you approve it, and risky approvals and known phishing sites are flagged first.
Which button do I pick on Best in Slot?
"Unisat". That is the entry Best in Slot showed for the wallet when we checked it on 2026-09-17. Sites change their menus, so if it has moved, look for Locker Protocol Wallet or the generic browser wallet entry.
Do I need a hardware wallet to use Best in Slot this way?
No. The key lives on the Locker Vault, a free app you install on a spare phone and keep offline. Transactions travel to it and back as QR codes, with no cable and no Bluetooth.
Does Locker Protocol Wallet add a fee on Best in Slot?
No. Using Best in Slot through the wallet costs only what Best in Slot and the network charge. The wallet's own fee applies to swaps and bridges made from the extension itself (at most 0.25%), shown before you sign.
